nope, if you do it through bmw that is the only way your correct. But if you do it through your performance mechanic, they can just replace those specifically. Theyre bolted onto the turbo with brackets, not welded- so I purchased them off ecstuning for about a 100 bucks a pop, had my mechanic replace all the oil lines (which stay in the car for the RB's) and replace both wastegates, and it worked like a charm. Stock car your gunna have no rattle at all, with a tune your always gunna have slight rattle and slight rattle is better then the loud RATTLE from a blown or worn out wastegate, which is what i had before.
